PURPOSE: To evaluate the incidence and the site of osteomas and their relation to sinonasal inflammation. MATERIALS AND METHODS: 1578 PNS computed tomography (CT) of patients with symptoms of sinusitis were evaluated and correlation with plain radiographic finding was done. RESULTS: The total incidence of osteomas was 0.82%(13/1578) on plain radiography and 3.29% (52/1578) on CT. Fifty-seven osteomas were found in 1578 PNS CT, including 2 osteomas in 5 cases. The most common site was the ethmoid sinus(54%, 31/57) and the next was the frontal sinus(35%, 20/57) on CT. Forty-five osteomas (78.9%) were associated with the sinonasal inflammatory change. CONCLUSION: The total incidence of osteomas from our results was higher than previous reports. And based on the analysis of CT, the most common site was not the frontal sinus as all the previous reports stated, but the ethmoid sinus, probably by virtue of high resolution of CT and/or higher prevalence of inflammation in the ethmold sinus.

Though the incidence of paragonimiasis has been remarkably decreased since 1970, it is still not a rare disease in Korea. Major problems in the diagnosis of pulmonary paragonimiasis on chest radiography are its differentiation from pulmonary tuberculosis and lung cancer. Chest radiographic findings have been described in detail, but little have been reported on CT findings. We reviewed CT findings of 10 patients with pulmonary paragonimiasis. The characteristic CT findings were similar to those on chest radiography, such as air-space consolidation (70%), nodular mass (50%), pleural effusion (40%), cystic lesion (30%), small low density within the mass (30%), linear density (20%), pneumothorax(20%), and burrow track (20%). CT depicted the cystic lesions and the burrow tracks more clearly and showed the small worm-retaining cysts within the mass that were not detectable on chest radiography. In conclusion, all of these CT findings are useful in the diagnosis of pulmonary paragonimiasis especially when differentiation from tuberculosis or lung canceris difficult on chest radiography.

PURPOSE: The purpose of this study was to construct a measurement instrument for climacteric symptoms among Korean and Japanese women. METHODS: From Dec. 1st of 2003 to March 30th of 2004, in-depth interviews were made with 26 women (15 in Jinju, Korea and 11 in Nagasaki, Japan) aged from 45 to 59 years who had not taken hormone replacement therapy to relieve the climacteric symptoms. A draft questionnaire with 45 items was constructed on the basis of the interview data and literature review. Three obstetricians, three PhDs in nursing science, and a chief nurse who was exclusively in charge of the climacteric management, examined the draft questionnaire to evaluate content validity. After deletions 39 items remained for a preliminary questionnaire. A survey was conducted by using a convenient sampling method in Jinju of Korea and Nagasaki of Japan during the period from April 1st, 2004 to July 10th, 2005. RESULTS: Factor analysis identified 4 factors, which were "mental and psychological symptoms", "physical symp-toms", "loss of autonomic nervous system symptoms", "sexual symptoms". These four factors explained 46.9% of total variance. CONCLUSIONS: The results demonstrated that climacteric symptom scale was multidimensional, and the reliability and validity of the scale was supported.

PURPOSE: The benefit of consolidation high-dose chemotherapy (HDC) for high-risk primary breast cancer is controversial. We evaluated the efficacy and safety of consolidation HDC with cyclophosphamide, thiotepa and carboplatin (CTCb) followed by autologous stem-cell transplantation (ASCT) in resected breast cancer patients with 10 or more positive lymph nodes. MATERIALS AND METHODS: Between December 1994 and April 2000, 22 patients were enrolled. All patients received 2 to 6 cycles of adjuvant chemotherapy after surgery for breast cancer. The HDC regimen consisted of cyclophosphamide 1, 500 mg/m2/day, thiotepa 125 mg/m2/day and carboplatin 200 mg/m2/day intravenous for 4 consecutive days. RESULTS: With a median follow-up of 58 months, 11 patients recurred and died. The median disease-free survival (DFS) and median overall survival (OS) were 49 and 69 months, respectively. The 5-year DFS and OS rates were 50% and 58%, respectively. The 12 patients with 10 to 18 involved nodes had better 5-year DFS (67%) and OS (75%) than 10 patients with more than 18 involved nodes (30% and 38%, respectively). The most common grade 3 or 4 nonhematologic toxicity was diarrhea, which occurred in 5 patients (23%). No treatment-related death was observed. CONCLUSION: Consolidation HDC with CTCb followed by ASCT for resected breast cancer with more than 10 positive nodes had an acceptable toxicity but does not show promising survival.

PURPOSE: The benefit of high-dose chemotherapy (HDC) for metastatic breast cancer (MBC) is controversial. We evaluated the efficacy and safety of HDC with cyclophosphamide, thiotepa, and carboplatin (CTCb) followed by autologous stem-cell transplantation (ASCT) for MBC patients. MATERIALS AND METHODS: From September 1994 to December 1999, 23 MBC patients were enrolled. All the patients received 2 to 10 cycles of induction chemotherapy. Before transplantation, 12 patients were in complete response (CR), nine were in partial response (PR), and two had progressive disease (PD). The HDC regimen consisted of cyclophosphamide 1, 500 mg/m2/day, thiotepa 125 mg/m2/day and carboplatin 200 mg/m2/day intravenously for 4 consecutive days RESULTS: After ASCT, 13 patients (56%) had a CR, five (22%) had a PR, three (13%) had no change, while two (9%) showed a PD. Seventeen patients relapsed or progressed during the median follow-up of 78 months. The median progression-free survival (PFS) time was 11 months and the median overall survival (OS) time was 23 months. The 5-year PFS and OS rates were 22% and 25%, respectively. On the multivariate analyses, less than 4 involved lymph nodes was predictive of a better PFS and OS. CONCLUSION: HDC with CTCb for MBC has acceptable toxicity; however, this treatment does not show a survival benefit.

We investigated the effectiveness of lamivudine to prevent hepatitis flare up due to reactivation of hepatitis-B virus (HBV) in hepatitis-B surface antigen (HBsAg)-positive patients with Non-Hodgkin's lymphoma (NHL) during cytotoxic chemotherapy. HBsAg-positive patients with NHL were identified from the lymphoma database of the Asan Medical Center from January 1995 to August 2002, and their medical records were reviewed. We found that 31 patients were received cytotoxic chemotherapy among 41 NHL patients with HBsAg-positive during same period. We divided them into 2 groups of HBsAg patients with NHL as follows: Group A who received cytotoxic chemotherapy with lamivudine 100 mg daily; Group B without any prophylactic antiviral therapy. There were no significant differences between Group A and B in several clinical variables. Seventeen patients (85%) in group B and one patient (9%) in Group A had hepatitis due to reactivation of HBV (p<0.001), with one hepatic failure related death in Group B and none in group A. The mean dose intensity of adriamycin actually delivered was 13.3 mg/m2/week (80% Relative Dose intensity (RDI)) in Group A and 9.1 mg/m2/week (55% RDI) in Groups B (p<0.001). Our data suggest that the frequency of chemotherapy-related HBV reactivation may be significantly decreased by lamivudine prophylaxis with maintenance of the dosage of adriamycin.

Although high-dose therapy (HDT) with autologous hematopoietic stem cell transplantation (ASCT) is widely accepted as an effective and safe consolidation therapy for multiple myeloma (MM), few reports on its efficacy are available in Korea. We present the results of a prospective phase II study, involving 33 patients with MM treated with HDT with ASCT. The treatment consisted of 4 courses of VAD (vincristine, adriamycin, dexamethasone) induction, peripheral blood stem cell collection, and high-dose melphalan with stem cell infusion. The overall response rate was 93%, with 45% of patients having complete responses. The toxicity was predictable and tolerable. With a median follow-up of 27.6 months, the 2-year event free survival rate was 43%. At the time of writing, the median overall survival duration had not been reached with 2-year survival and projected 3-year survival rates of 81% and 74%, respectively. The overall survival was significantly better than that of the historical control patients (N=82) treated with conventional chemotherapy at our institution. The results suggest that HDT with ASCT is a valuable first or second-line treatment for patients with MM.

BACKGROUND: We performed this study to compare response rate and survival according to treatment modalities, such as allogeneic bone marrow transplantation (BMT), immunosuppressive therapy (IS) and androgen therapy in patients with aplastic anemia (AA). METHODS: Medical records of one hundred and thirty-seven patients who diagnosed with aplastic anemia at the Asan Medical Center from September 1989 to December 2000 were retrospectively analyzed. RESULTS: Forty-one patients received supportive care only. Ninety-five out of 96 treated patients were evaluable for response. In severe AA group (N=79), the response rate according to treatment modalities was 25.0% in the androgen group (N=4), 30.3% in the ALG or ATG group (N=33), 25.0% in the cyclosporine (CSA) group (N=8), 44.4% in the ATG plus CSA group (N=9), and 73.8% in the BMT group (N=23) (P<0.001). Five- and 10-year survival of overall patients was 67.5% and 50.9%, respectively. Ten-year survival according to disease severity was 42.3% in severe AA group and 75.8% in non-severe AA group (P=0.0043). Five- year survival according to treatment modalities in patients with severe AA was 75.0% in the androgen group, 49.0% in the ALG or ATG group, 75.0% in the CSA group, and 88.9% in the ATG plus CSA group. Five-year survival was 82.6% in the BMT group and 57.7% in the IS group (P=0.0259). CONCLUSION: This study showes that BMT resulted in significantly better response rate and overall survival compared to IS in patients with severe AA.
